There is a person, lying on the burning sand, not even particularly arranging himself for less sand contact, eyes closed against the light, whimpering a little involuntarily now and again. He wasn't there the last time she checked.
He says the same sound again.
She repeats just that sound again.
He doesn't say anything this time.
....she can try the sounds she made before, again?
That gets a repeat.
She can repeat some of the other sounds he made when he was asleep and see if he responds to any of those?
Not most of them.
He does make a new sound after she's gone through about fifty.
She repeats that sound!
He repeats it too!
She doesn't really know what to do with this.
She.... repeats the response-sound he made the first time?
She... repeats both of the response sounds one after the other?
Hmmmm. There's probably a pattern but she isn't sure what it is.
She tries the sound that got him to make the first response sound.
First response sound.
She makes both of the response sounds at the same time, one coming from her left and one coming from her right.
He opens his eyes for a moment and then closes them again and doesn't say anything.
She goes back to repeating sounds she heard before in random orders.
Sometimes she will get First Response Noise, sometimes she will get Second Response Noise.
It's weird how he makes more sounds when he's asleep than when he's awake. She wonders whether she makes more sounds when she's asleep.
Eventually she flies away. When she comes back she has a little bone flute.
He doesn't react to that.
She plays the flute. Maybe this will provoke more sounds?
He turns his head a bit, but he doesn't say anything.
She plays for a while and then goes back to repeating the set of sounds she's heard him say.
The sounds that get a particular response seem to get it consistently and the others get nothing.
